Core tips

On June 18, 46 graduate students from Renmin University of China suffered from eye swelling and facial pain after eating in Xiaoshizao Restaurant in Ximen, and1student was more serious, and their blood was abnormal after being examined by the hospital. Doctors say that prolonged exposure to ultraviolet rays may lead to skin cancer in the future.

At present, 46 students are caught in a skin cancer panic. Although they are facing graduation, they are not only talking about work, but also asking each other about the progress of their illness.

Afterwards, it was learned that these students were inadvertently exposed to ultraviolet rays, causing physical harm.

However, when people go to restaurants to eat, who will pay attention to whether there is ultraviolet light on their heads? !

According to the survey, most consumers usually pay attention to the food on their plates when eating in restaurants, but just ignore this situation.

According to the introduction of relevant health departments, there are few complaints about accidents caused by citizens and customers, and there are no specific regulations on the sale and use of this product.

On June 25th, Zhao, a female graduate student in the Department of Business Administration of Renmin University of China, told the reporter that although the peeling situation has improved, they are worried that they will leave sequelae or something, just waiting for the results of the review on June 28th.

The injured students will be reexamined today.

Zhao said that the students in his class got sick collectively after eating in Xiaoshizao Restaurant on June 18, and went to the Third Hospital of Beijing Medical University on June 19, and the result was ultraviolet radiation induced ophthalmia.

She said that on the morning of June 2 1, more than 30 students went to the China-Japan Friendship Hospital in Chaoyang District, and the peeling phenomenon increased significantly, reaching more than 20 people. The results showed that 1 1 human blood was abnormal. The doctor told them that after such a long time of irradiation, their skin was more likely to become cancerous, and asked them to check again next week. She said that the students in the class seem to have nothing serious now, but they are all worried about what will happen in the future. Although most of them have left, they are not in the mood to think about leaving school.

It's the first time for me to have symptoms in Beijing.

Dr. Zhang, who was on duty at the China-Japan Friendship Hospital at that time, said that such symptoms were discovered for the first time in Beijing, that is, in medical experiments, human experiments are generally irradiated for a few minutes, which will not affect human health, and even mice irradiated for 20 minutes will have obvious adverse symptoms, so it depends on whether there are any abnormal symptoms. Dr. Zhang said that after being exposed to so many people for so long, there is a great possibility of cancer. Ultraviolet radiation is harmful to internal tissues. If it's just peeling, it can be cured by applying some medicine. However, the long-term observation of internal organizations must establish files, and there is no research in this field in China.

As of press time, the test results made by the staff of the Health Bureau in Xiaoshizao Hotel have not yet come out.

Reporter's survey: Most diners only care about eating and don't care about lights.

The public said that when eating in hotels, they generally don't pay attention to whether there are disinfection lights.

In response to this incident, the reporter interviewed some citizens and relevant departments and found that most citizens knew little and didn't care much.

Citizen: Don't pay attention to the disinfection lamp when eating.

Forty-six graduate students of the National People's Congress were accidentally injured by disinfection lamp irradiation. According to the reporter, many citizens generally don't notice whether the hotel is equipped with external environment such as disinfection lights when they enter the hotel for dinner.

On the evening of June 19, when the reporter told two customers who were dining in Xiaoshizao restaurant about the disinfection lamp, they looked up at the lamp on the ceiling and said, "We didn't pay attention. If you didn't tell us, we didn't pay attention. Now that you mention it, we feel that the lights are dazzling. " One of the customers said that he didn't care if there was a disinfection lamp, because there was little or no contact at ordinary times. Miss Chen, who dined in a restaurant in Hufangqiao, said that she only went to the hotel restaurant for dinner or entertainment, and basically didn't care if there were disinfection lights.

Hotels: Most of them are installed in workshops.

When interviewed in some hotels, restaurants and other public places in Beijing, the reporter found that most public places are equipped with disinfection lamps, but most of them are installed in kitchens and closed workplaces.

At noon the day before yesterday, the reporter saw in a restaurant in Wei Bei Road, Xuanwu District that a mosquito killer was installed in the business hall, and the disinfection lamp was only installed in the cold room of the kitchen. Manager Cheng of the restaurant said that the whole restaurant is only equipped with a disinfection lamp in the cold room, with an irradiation power of 40 watts, which is mainly used to prevent the growth of bacteria and disinfect for half an hour after work every night. He said that people turned on the light and left because it was poisonous.

Some restaurants said that in order to disinfect, disinfection lamps are generally used, but the disinfection lamps are installed in the workshop, not in the business hall. They say that as long as it is used correctly, it will generally not cause harm to the body.

Doctor: Try to avoid long-term exposure.

Li Donghui, an ophthalmologist at Peking Union Medical College Hospital, said that ultraviolet light is light with a wavelength of more than 7 10 angstrom, and exposure for about 10 minutes is no problem. But after a long time, it will damage the retina and skin, causing eye diseases such as electro-optic ophthalmia. Li Donghui said that users should use disinfection lamps in strict accordance with the instructions. For example, it should be noted that people's eyes and skin will be burned when exposed to ultraviolet rays for a long time, so the operator must wear protective equipment. If the disinfection lamp is not used for a long time, it should be stored in a dry and corrosion-free environment, especially in the kitchen.

Department statement: sales do not need any department approval yet.

A person concerned in the health department said that the current sales are relatively loose and there are few related complaints.

Regarding the installation and use of disinfection lamps, Sun of Haidian District CDC said in an interview that the use of disinfection lamps in hotels is not expressly stipulated, and it is also strictly prohibited to use them in karaoke rooms in relevant environmental sanitation regulations. For the sale of disinfection lamps, it is now unwritten practice to sell them in some specialty stores approved by the health department, but other stores are not prohibited from selling them.

According to the staff of the Disinfection Department of Beijing Health and Epidemic Prevention Station, the production regulations of ultraviolet disinfection lamps are quite strict and must be approved by the Ministry of Health, but the sales are relatively loose and do not need the approval of any department. He said that there is no rule that it cannot be used in hotels at present, but it must be used correctly.

The reporter interviewed the health supervision offices in Xuanwu and Daxing by telephone. The staff replied that they had never received such complaints, and Chaoyang Health Supervision Office had never received similar complaints. They also said that there was a public health complaint center in Beijing, and complaints about public health were accepted by the complaint center.

The reporter then interviewed the center. According to a staff member surnamed Zhu, this kind of complaints received by the center are quite few, because users generally know that ultraviolet disinfection lamps can't illuminate people when they are used, so ultraviolet injury incidents rarely occur. She said that if complaints are received, they will be transferred to the health supervision offices in various districts (counties) for handling. The Ministry of Health shall, jointly with relevant departments, inspect disinfection lamp products every year to ensure the quality of lamps is qualified.

Noun interpretation

The ultraviolet disinfection lamp uses ultraviolet rays to kill bacterial propagules, spores, mycobacteria, coronavirus, fungi, rickettsia and chlamydia. All surfaces, water and air contaminated by the above viruses can be disinfected by ultraviolet rays.

At present, the ultraviolet disinfection lamp used in China has high irradiation intensity and farther disinfection and sterilization effect. When using, it must be used in an unmanned state to avoid long-term contact with human eyes and skin.
